I wanna convert image to vector but not vector file (.ai) same image with same format I mean clean all shadow and thing like it or have clear image with only some clear shape like circle ... or like cutout filter in photoshop in other way Can we use photoshop filter in our program.

An image can not simple be a vector format. a vector image as you may know is more like a series of instructions that are executed to draw the image. as this is the case you need a specific program that understands these 'instructions' and can render the image appropraitely.
I think what you want to do is look at image processing techniques. Im sure it would'nt take much of your time to do a search, i bet all the photoshop filter algorithms are floating around the internet somewhere.

Hi,
I've suddenly started getting an incomprehensible threading error message when I try to use the standard open-file dialog:
"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."
But my Main method DOES have "[STAThread]" preceding it. The online help goes into extensive detail on the complexities of apartment models, but doesn't give me a clue what could be causing this exception. Any ideas? Thanks!
|
|
|
|
|
And is the code launching the dialog running on the UI thread?
|
|
|
|
|
Yes; there is only one thread, which is started by the Application.Run () method from Main ().
|
|
|
|
|
Hmm, what does the debugger show if you break into the GUI thread and type System.Threading.Thread.CurrentThread.ApartmentState at the Watch window?
COM apartment state can be set only once per thread, so if someone (VS?) sets the apartment to something else, the STAAttribute won't help.

As mentioned in the post below, I was able to make the problem go away by reverting to an earlier version. Thanks for the suggestion, though.
|

|

"Solved" the problem by reverting to an earlier version, before the bug appeared, then copying the changed source files over the earlier version to update. The problem disappeared. I'll probably never know what caused it.

I couldn't connect to a named instance of SQL 2005 the last few days from VS2005. I tried everything but failed ("Instance Failure"). Today, I simply changed the Data Provider from SQL Server to OLE DB and it worked.
Any idea how I can fix this problem. I have many applications which are using SQL Server as the provider and changing them is not an option--at least if there is another option.

It was working and then just stopped? You really want to use the SqlServer data provider rather than that OLE DB thing provider when using SQL server if you can.
Sorry if I'm stating the obvious, but have you definitely got the connection string correct?

Yes, connection string is definitely correct because it used to work but after DBAs installed SQL Server, the applications stopped working.

Have you checked all the appropriate protocols are open in the configuration manager?

Here you go:
Name:Order:Enabled
Shared Memory:1:Enabled
TCP/IP:2:Enabled
Named Pipes:3:Enabled
VIA::Disabled
Everything enabled except for VIA.

I've run out of ideas then. The named instance hasn't changed?

No.
I don't understand why VS2005 can connect using OLE DB but not SQL as Data Provider. This is where the problem resides: If we can figure out why one works and the other does not.

Solved!!!!
Default instance and named instance were both listening on the same port number. I asked the DBAs to change the port number of the named instance to a different port and all is fine now.
Shouldn't the DBA's fix this? They kept saying it is my applications.

Hallo,
I'm looking for a way to read the table of contents of an ms word document and load it in a richtextbox, with c# and visual studio 2005. Is there a way to make it linkable (if someone klicks on it, it takes you to the specific page)???
If it's not possible with a richtextbox, is there any other tool that can do it??
Thanks!!

Hi Guys,
Quick question : I have 2 forms : FORM1 and FORM2. In FORM1 i am trying to implemen a PRINT PREVIW button to work like the PRINT PREVIW button in FORM2.
Here is the delegate, event Starter() and Subscriber() lines.
public delegate void DelegatPrintPreview(object sender, EventArgs e);
public static event DelegatPrintPreview EvenimentDelegatPrintPreview;
public static void StarterPrintPreview(object o, EventArgs ev)
{
if (EvenimentDelegatPrintPreview != null)
{
EvenimentDelegatPrintPreview(o, ev);
}
}
public static void SubscribeToPrintPreview(DelegatPrintPreview pf)
{
EvenimentDelegatPrintPreview += new DelegatPrintPreview(pf);
}
the question is : Where do i put the delegate(in the form with the same button or the other one )? and the same question with the Starter() and Subscriber() methods ?
Regards,
Alex

Firstly, you don't need to define that delegate. The EventHandler delegate has the same signature.
http://msdn.microsoft.com/en-us/library/system.eventhandler.aspx[^]
You'd want to stick your event handler in both forms, and implement each seperately. If they share the same code, put that in a common function and call that from both handlers.

10x for the advice Rob. My delegate works just as it is. The issue is that Form1 is the first that starts when i run the program . In form 2 i have the button to print ( with the code). To avoid copying the same code in Form1, i wanted to create a delegate. So i created it in Form2 and also subscribed the print preview method to in in Form2. I made it but it only works when i start Fom1 and then start form2 and close it. Then i can use the button in Form1 for print preview.
This is because when i use the starter method in Form1 for the button in the Menu Strip i run it like this :
private void printPreviewToolStripMenuItem_Click(object sender, EventArgs e)
{
Form2.StarterPrintPreview(sender, e);
}
So it needs form2 started once in order to run...and i am struggling with this to make it work 
PS:I declared the Methods in Form2 STATIC but i can't see them in form1.i need to call them using FORM2

Did you make them public/internal?
If the code doesn't logically belong to Form2, how about having a separate static class that has the common code?

I'm very much with Senthil's comments above. You really don't want some common functionality in form code. Otherwise, as your experiencing you need to create form2 in order to do print preview in form1. form2 has obviously got massive amounts of GUI stuff in it which you don't need or want.
Try and abstract out the preview functionality into another class and call that from both.

Rob Philpott.
